[0024] Embodiments of the present invention will now be described with reference to the accompanying drawings, wherein like reference numerals represent like elements throughout the several views.

[0025] See also Figure 1 The horizontal multi-roller circulating aluminum rod heating furnace 100 of the present invention comprises a furnace body 10a, a circulating fan 10b, a circulating pipe 10c, a heat exchanger 10d, a combustion system 10e, a feeding clamping mechanism 20, a rod pushing mechanism 30, a discharging clamping mechanism 40, a feeding roller 50a, a discharging roller 50b and an aluminum rod batch discharge mechanism 60. The combustion system 10e is installed on the furnace body 10a, and the furnace body 10a provides support for the combustion system 10e; the first end of the combustion system 10e is connected to the furnace body 10a to irradiate the aluminum rod 200 (see Figure 6 ) for processing. The first end of the circulation pipe 10c is installed on the furnace body 10a, and the furnace body 10a provides support for the circulation pipe 10c; the circulation pipe 10c is also connected to the furnace body 10a. The heat exchanger 10d is respectively connected to the second end of the combustion system 10e, the second end of the circulation pipe 10c and the circulation fan 10b. The feed roller 50a is located outside the furnace body 10a and is connected to the first end of the furnace body 10a (for example, but not limited to) along the length direction of the furnace body 10a (i.e., the direction indicated by the double arrow A). Figure 1 The right end of the docking, preferably, Figure 3 In the embodiment, the feed roller 50a is connected to the first end of the furnace body 10a in a straight line, so that the aluminum rod 200 on the feed roller 50a is aligned with the inlet 18 of the furnace body 10a, thereby facilitating the aluminum rod 200 to be pushed into the multi-roller conveyor line 17 installed in the furnace body 10a. The discharge roller 50b is located outside the furnace body 10a and is connected to the second end (for example, but not limited to) of the furnace body 10a along the length direction of the furnace body 10a. Figure 1 The left end of the docking is preferably Figure 3In the embodiment, the discharge roller 50b is connected to the second end of the furnace body 10a in a straight line, so that the discharge roller 50b corresponds to the discharge port 19 of the furnace body 10a, so that the multi-roller conveyor line 17 in the furnace body 10a can convey the aluminum rod 200 to the discharge roller 50b. The push rod mechanism 30 is located on the side of the feed roller 50a away from the first end of the furnace body 10a. The push rod mechanism 30 is used to push the aluminum rod 200 on the feed roller 50a into the furnace body 10a. For example, the push rod mechanism 30 can be composed of a push rod cylinder or a push rod oil cylinder, but it is not limited to this. The feed clamping mechanism 20 crosses the feed roller 50a from above the feed roller 50a along the width direction of the furnace body 10a (i.e., the direction indicated by the double arrow B), so that the feed clamping mechanism 20 can place the aluminum rod 200 on the feed roller 50a. The aluminum bar batch discharge mechanism 60 is located next to the feeding clamping mechanism 20 and is aligned with the feeding roller 50a along the width direction of the furnace body 10a. This design can reduce the travel path of the feeding clamping mechanism 20 to grab the aluminum bars 200 on the aluminum bar batch discharge mechanism 60 and place them on the feeding roller 50a, so that the feeding clamping mechanism 20 can quickly and reliably transfer the aluminum bars 200 on the aluminum bar batch discharge mechanism 60 to the feeding roller 50a one by one in an orderly manner. The discharging clamping mechanism 40 crosses the discharging roller 50b from above the discharging roller 50b along the width direction of the furnace body 10a, so that the discharging clamping mechanism 40 can grab the aluminum bars 200 on the discharging roller 50b and discharge them along the width direction of the furnace body 10a. Specifically, Figure 1 and Figure 3In the embodiment, since the feed port 18 and the discharge port 19 each have three layers, and each layer consists of four aluminum bars arranged in a row, in order to align the aluminum bars 200 on the feed roller 50a with the feed port 18 in each layer, and the discharge roller 50b corresponds to the discharge port 19 of each layer, the horizontal multi-roller circulating aluminum bar heating furnace 100 of the present invention further includes a feed lifting platform 80a and a discharge lifting platform 80b, the feed lifting platform 80a is located directly below the feed roller 50a, the feed roller 50a is installed on the feed lifting platform 80a, and the feed roller 50a drives the feed roller 50a to move upward. The material roller 50a is lifted up and down, so that the aluminum bars 200 on the material roller 50a can be aligned with the material inlet 18 in each layer; the material discharging lifting platform 80b is located directly below the material discharging roller 50b, and the material discharging roller 50b is installed on the material discharging lifting platform 80b, and the material discharging lifting platform 80b drives the material discharging roller 50b to lift up and down, so that the material discharging roller 50b can correspond to the material discharging port 19 in each layer, so as to ensure that the aluminum bars 200 on the multi-roller conveyor line 17 in the furnace body 10a are reliably conveyed to the material discharging roller 50b. Since the material inlet 18 and the material discharging port 19 are three layers each and four on each layer, correspondingly, the multi-roller conveyor line 17 is also three layers and four aluminum bars 200 are conveyed on each layer, and correspondingly, the push rod mechanism 30 is installed on the material discharging roller 50a, and the push rod cylinder or push rod oil cylinder in the push rod mechanism 30 is also four arranged in a row. It is understandable that in other embodiments, the feed inlet 18 and the discharge outlet 19 may each be one layer, two layers or multiple layers, and each layer may be two, three or more layers, so it is not limited to this. More specifically, as follows:

[0026] like Figure 3 As shown, the interior of the furnace body 10a has a preheating zone 11, a heating zone 12, a heat preservation zone 13 and a constant temperature zone 14 connected in sequence along the direction of the furnace body 10a close to the discharge roller 50b. The preheating zone 11, the heating zone 12, the heat preservation zone 13 and the constant temperature zone 14 are respectively provided with a combustion system 10e, a circulation fan 10b, a circulation pipe 10c and a heat exchanger 10d to improve the processing effect of the aluminum rod 200. Specifically, in Figure 2 and Figure 3 In the figure, the top of the furnace body 10a is a cover structure 16, and the cover structure 16 is divided into four sections along the length direction of the furnace body 10a. The preheating zone 11, the heating zone 12, the insulation zone 13 and the constant temperature zone 14 each correspond to a section of the cover structure 16, so as to facilitate the maintenance of the horizontal multi-roller circulating aluminum rod heating furnace 100 of the present invention.

Preferably, the first end of the circulation pipe 10c is installed at the lower part of the side wall 15 of the furnace body 10a, and the first end of the combustion system 10e is installed at the upper part of the side wall 15 of the furnace body 10a to achieve the purpose of lateral circulation; and the heat exchanger 10d is installed at the second end of the circulation pipe 10c, and the circulation fan 10b is installed on the heat exchanger 10d. This arrangement avoids the circulation fan 10b and the heat exchanger 10d being installed on the top of the furnace body 10a and affecting the top cover structure 16.

[0028] like Figure 4 and Figure 5 As shown, the feeding clamping mechanism 20 includes a gantry support 21, a walking frame 22, a lifting support 23, a clamping device 24, a lifting motor 25 and a lifting reduction box 26.

The walking frame 22 is equipped with lateral walking wheels 221 that clamp the walking track 212 from opposite sides of the walking track 212 (i.e., the two sides of the walking track 212 separated in the length direction of the furnace body 10a) and top walking wheels 222 that roll against the walking track 212 from above the walking track 212, so that the walking frame 22 can move more flexibly and smoothly on the crossbeam 211 with the cooperation of the lateral walking wheels 221 and the top walking wheels 222. The upper end of the lifting bracket 23 is equipped with a lifting rack 27 arranged along the height direction of the furnace body 10a (i.e., the direction indicated by the double arrow C), and the lifting reduction box 26 is installed on the walking frame 22, and the walking frame 22 provides support for the lifting reduction box 26; the input end of the lifting reduction box 26 is assembled and connected with the lifting motor 25, and the output end of the lifting reduction box 26 is equipped with a lifting gear 28 that meshes with the lifting rack 27, and the clamping device 24 is assembled at the lower end of the lifting bracket 23. Therefore, under the operation of the lifting motor 25, the lifting gear 28 is driven to rotate through the lifting reduction box 26, so that the lifting gear 28 obtains a larger torque; and the rotating lifting gear 28 drives the lifting rack 27 together with the lifting bracket 23 and the clamping device 24 on the lifting bracket 23 to rise and fall together, so as to meet the movement needs of the clamping device 24 to grab or put down the aluminum rod 200. Specifically, Figure 4 and Figure 5In the figure, the walking skeleton 22 includes a walking mounting seat 22a and a hollow walking frame 22b; the walking mounting seat 22a is overlapped with the cross beam 211 from above the cross beam 211, the lateral walking wheels 221 and the top walking wheels 222 are installed on the walking mounting seat 22a, and the walking frame 22b is overlapped with the cross beam 211 from the side of the cross beam 211. This design makes the assembly between the walking skeleton 22 and the cross beam 211 more reasonable and compact, and ensures that the walking frame 22b is more reliably supported by the cross beam 211; the lifting bracket 23 is inserted into the walking frame 22b, and the lifting reduction box 26 is installed at the walking frame 22b.

[0029] At the same time, Figure 4 and Figure 5In the embodiment, the clamping device 24 includes a clamping driver 241, an upper and lower push-pull block 242, a first connecting rod 243, a second connecting rod 244, a third connecting rod 245, a fourth connecting rod 246, a first mounting shaft 247, a second mounting shaft 248, a first clamping plate 249a and a second clamping plate 249b. The first mounting shaft 247 and the second mounting shaft 248 are separated and parallel to each other along the width direction of the furnace body 10a. Preferably, the first mounting shaft 247 is also aligned with the second mounting shaft 248 in the width direction of the furnace body 10a. The third connecting rod 245 can be pivotally mounted on the first mounting shaft 247 around the first mounting shaft 247. Preferably, the middle part of the third connecting rod 245 is mounted on the first mounting shaft 247, but not limited thereto. The fourth connecting rod 246 can be pivotally mounted on the second mounting shaft 248 around the second mounting shaft 248. Preferably, the fourth connecting rod 246 can be pivotally mounted on the second mounting shaft 248 around the second mounting shaft 248. The middle part of 46 is sleeved on the second mounting shaft 248, but not limited to this; the upper and lower push-pull blocks 242 are located directly above the first mounting shaft 247 and the second mounting shaft 248; the clamping claw driver 241 is installed on the lifting bracket 23 and is located directly above the upper and lower push-pull blocks 242, the output end 241a of the clamping claw driver 241 is also arranged downward, and the upper and lower push-pull blocks 242 are installed on the output end 241a of the clamping claw driver 241; the first end of the first connecting rod 243 is hinged to the first side of the upper and lower push-pull blocks 242, and the second end of the first connecting rod 243 is hinged to the third connecting rod 2 The upper end of the third connecting rod 245 is hinged, and the first clamping plate 249a is installed at the lower end of the third connecting rod 245; the first end of the second connecting rod 244 is hinged to the second side of the upper and lower push-pull blocks 242, and the second end of the second connecting rod 244 is hinged to the upper end of the fourth connecting rod 246, and the second clamping plate 249b is installed at the lower end of the fourth connecting rod 246, and the second clamping plate 249b is aligned with the first clamping plate 249a along the width direction of the furnace body 10a; therefore, in the process of the clamping claw driver 241 driving the upper and lower push-pull blocks 242 to slide up and down, through the first connecting rod 243 and the third connecting rod 245 To drive the first clamping plate 249a to pivot around the first mounting axis 247 to move closer to or away from the second clamping plate 249b. At the same time, the second connecting rod 244 and the fourth connecting rod 246 are used to drive the second clamping plate 249b to pivot around the second mounting axis 248 to move closer to or away from the first clamping plate 249a, so that the first clamping plate 249a and the second clamping plate 249b can coordinate with each other to open and close, thereby achieving the purpose of more reliable clamping of the aluminum rod 200. For example, the clamping claw driver 241 is a cylinder to provide a greater clamping force, but it is not limited to this. It is understandable that since the structure of the material discharging clamping mechanism 40 is exactly the same as that of the material feeding clamping mechanism 20, the structure of the material discharging clamping mechanism 40 can refer to the material feeding clamping mechanism 20, so the material discharging clamping mechanism 40 will not be described in detail.

[0030] like Figure 6As shown, the aluminum bar batch discharge mechanism 60 includes a lifting support discharge rack 61, a lifting drive 62 and an outer frame 63. The lifting support discharge rack 61 is respectively installed with lifting wheels 64 on the first side and the second side spaced apart in the width direction of the furnace body 10a, and the lifting wheels 64 are rollingly matched with the outer frame 63. Such a design improves the flexibility and smoothness of the lifting support discharge rack 61 sliding up and down on the outer frame 63; the lifting drive 62 is located at the corresponding lower part of the lifting support discharge rack 61, and the lifting drive 62 is also assembled on the lifting support discharge rack 61 and the outer frame 63. Preferably, there are two lifting drives 62 and they are spaced apart and aligned in the length direction of the furnace body 10a, and each lifting drive 62 is assembled on the lifting support discharge rack 61 and the outer frame 63. Such a design improves the reliability of the lifting drive 62 lifting or lowering the lifting support discharge rack 61. For example, the lifting drive 62 is a cylinder or an oil cylinder, so it is not limited to this.
